No leakage when making valve closing, it is achieved the function of stop valve.
3, the current on time of pneumatic administration valve is up to 100%, is much higher than current on time and only has the electromagnetism of 40% to be administered valve so that
Valve dosage is big and will not be burned.
4, the outside of throttle orifice is equipped with disconnected medicine inspection slowdown monitoring switch, its signal is delivered to be administered PLC, PLC and just can detect that signal
Compare with scope set in advance, when detecting that signal exceeds setting value, i.e. send alarm signal；Valve has feedback merit
Can, fill up electromagnetism and be administered the blank of valve feedback-less always；Disconnected medicine inspection slowdown monitoring switch is also not directly contacted with medicament, and is mounted in joint
Outside discharge orifice so that switch can be durable in use.
5., when being more than 12 millimeters for snack made with traditional Chinese medicines addition more than 8000 ml/min or throttle orifice, both valve external forms are complete
As Quan, such addition is different also be may be installed together, and the most neat.
In sum, this utility model is that one can judge whether disconnected medicine and good sealing effect, length in service life, installation side
The most neat pneumatic administration valve gear.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the present utility model.
Fig. 2 is the second structural representation of the present utility model.
Fig. 3 is the structural representation that existing electromagnetism is administered valve gear.
Fig. 4 is the structural representation of existing pneumatic cone valve device.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
It is typically all the electromagnetism administration valve gear used as shown in Figure 3 to complete.It by valve cover 1, coil 2, spool 3,
The parts compositions such as valve body 4, short circuit 5 and throttle orifice 6, are made up of PVC material, acid-alkali-corrosive-resisting.It is by the charged generation of coil 2
Magnetic picks up spool 3 allows it leave throttle orifice 6, and the liquid in valve body 4 flows out from throttle orifice 6 and realizes what liquid added, by
Less in the suction of electromagnetic valve, the pressure in valve body 4 can not be excessive, and the liquid level of general medicine-chest exists from valve inlet centre-height
Within 0.4 meter.The sealing of valve be depending on spool 3 deadweight and with the machining accuracy of throttle orifice 6 contact surface, the most this kind of valve
The leakage rate of door is relatively big, and the current on time of valve is the highest.For indivedual additions higher than the snack made with traditional Chinese medicines of 4000 ml/min, use many valves
In parallel or employing pneumatic cone valve as shown in Figure 4 adds, and the pneumatic cone valve shown in Fig. 4 is by cylinder 7, valve base 8, connecting rod 9, connection
Pipe 12, manual ball valve 11, valve head 10, throttle orifice 6 form, so will result in need to increase the length of medicine-chest 13 or affect valve whole
The problems such as neat layout.
Seeing Fig. 1, cylinder connecting plate 14 upper end connects cylinder 7, and lower end connects valve body 4；Valve body 4 is provided with valve and enters
Mouthfuls 21, the lower end of valve body 4 connects throttle orifice 6, in the cylinder piston rod 18 of cylinder 7 is located at valve body 4 and align throttle orifice 6, gas
Cylinder piston rod 18 uses sealing ring 15, pad 16 and jump ring 17 to seal with the junction of cylinder connecting plate 14.The control end of cylinder 7
It is connected with being administered control PLC.Throttle orifice 6 connects disconnected medicine inspection slowdown monitoring switch seat 19, and disconnected medicine inspection slowdown monitoring switch seat 19 is provided with and aligns joint
Disconnected medicine inspection slowdown monitoring switch 20 outside discharge orifice 6, disconnected medicine inspection slowdown monitoring switch 20 uses communication connection with being administered control PLC.
Seeing Fig. 1, sealing ring 15 realizes valve body 4 inner liquid medicine body and cylinder piston rod 18 and the isolation of valve body 4 outer air；Peace
It is contained in the disconnected medicine inspection slowdown monitoring switch 20 outside throttle orifice 6 to be connected to be administered the PLC controlled, when disconnected medicine inspection slowdown monitoring switch 20 detects throttling
Have in hole 6 medicinal liquid body by time send signal to being administered control PLC, be administered PLC according to detecting that signal just can determine whether this valve
Whether break medicine.
See Fig. 2, when 12 millimeters are more than more than 8000 ml/min or throttle orifice 6 for snack made with traditional Chinese medicines addition, cylinder piston rod
The front end of 18 connects valve head 10.
Seeing Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this utility model has the following advantages compared with electromagnetism administration valve gear:
1, sealing ring 3 is resistant to oxidisability strong as concentrated sulphuric acid, in valve body 4 liquid preparation pressure be resistant to 3.5MPa with
On, the most this kind of valve both may be installed medicament chamber to also may be installed flotation device side on medicine-chest 13.Stop because medicament is tied
Dirt and block medicament conveying pipe problem.
2, the spool of valve is exactly the cylinder piston rod 18 that cylinder 7 drives, and valve opening and closedown are driven by cylinder 7 to be controlled
System so that No leakage during valve closing, it is achieved the function of stop valve.
3, the current on time of pneumatic administration valve is up to 100%, is much higher than current on time and only has the electromagnetism of 40% to be administered valve so that
Valve dosage is big and will not be burned.
4, the outside of throttle orifice 6 is equipped with disconnected medicine inspection slowdown monitoring switch 20, its signal is delivered to be administered PLC, PLC and just can detect that letter
Number compare with scope set in advance, when detecting that signal exceeds setting value, i.e. send alarm signal；Valve has feedback merit
Can, fill up electromagnetism and be administered the blank of valve feedback-less always；Disconnected medicine inspection slowdown monitoring switch 20 is also not directly contacted with medicament, and is mounted in
Outside throttle orifice 6 so that switch can be durable in use.
5., when being more than 12 millimeters for snack made with traditional Chinese medicines addition more than 8000 ml/min or throttle orifice, pneumatic administration valve arrangement changes
For as shown in Figure 2.Both valve external forms are just the same, and such addition is different also be may be installed together, and the most neat.
